PAPR reduction in OFDM
PAPR reduction in OFDM is a research topic within Electrical and Electronic Engineering. Science Explorer counts 15k research works in it since 1959. 11.3% of them reached the world's top 10% most cited for their field and year.
This cluster of papers focuses on peak-to-average power ratio (PAPR) reduction techniques for orthogonal frequency division multiplexing (OFDM) and multicarrier transmission systems. It covers various methods such as clipping, filtering, partial transmit sequences, companding, and waveform contenders for 5G networks. The cluster also explores the impact of nonlinear distortion, channel estimation, and spectral efficiency in the context of PAPR reduction.

How concentrated that is
The same countries as shares of everything the list above accounts for. A node where two countries do two thirds of the work and one spread evenly across twelve read alike as a ranking and not at all alike here.
